Lung nodules can be intervened with radiofrequency ablation, but it is important to note that not all nodules require radiofrequency ablation treatment. Radiofrequency ablation is a precise and minimally invasive treatment technique that uses the biological effect produced by heat or cold to directly cause irreversible damage or coagulative necrosis of tumor cells in the lesion tissue. Radiofrequency ablation is mainly used for the treatment of stage Ia and Ib non-small cell lung cancer that cannot tolerate surgery, but it is not recommended for tumors that are close to large blood vessels in the lungs. It is important to note that the treatment of lung nodules is a stepwise process. For high-risk nodules, surgical resection is mainly recommended. For intermediate-risk nodules with diameters between 5-15mm and no obvious malignant CT signs, they should be left untreated for the time being, and then reviewed after 3 months, and the nodules found to be growing should be resected promptly. For low-risk lung cancer nodules with a diameter of less than 5mm, it is recommended to review after one year, find growth in time for surgery, and review once a year without growth. When lung nodules are found, it is recommended that patients should seek medical treatment in time and listen to the advice of specialized doctors.
